1. A system for generating an object in a mixed reality space, the system comprising: a memory area associated with a computing device, the memory area including a shader component; and a processor that executes the shader component to: obtain a two-dimensional (2D) object having a face with four vertices; determine a thickness of one or more edges of the 2D object to be generated, the thickness based at least in part on a viewing vector and a normal vector for the 2D object; generate a rendered 2D object with the determined thickness, including rendering the one or more edges with one or more colors to emulate a lighting condition; and present the rendered 2D object in a mixed reality space.

2. The system of claim 1 , wherein the processor further executes the shader component to separately render a horizontal edge color and a vertical edge color of a horizontal edge and a vertical edge of the rendered 2D object, respectively.

3. The system of claim 1 , wherein the processor further executes the shader component to transform a camera world position to a local position of the 2D object in the mixed reality space.

4. The system of claim 3 , wherein the processor further executes the shader component to determine the one or more edges to render based at least in part on the transformed position.

5. The system of claim 1 , wherein the processor further executes the shader component to use a dot product to calculate a cosine of horizontal and vertical angles between the viewing vector and the normal vector to determine the thickness of the one or more edges.

6. The system of claim 5 , wherein the processor further executes the shader component to modify a result of the dot product based at least in part on a scaling factor such that the thickness of the one or more edges is independent of the scale of the 2D object.

7. The system of claim 6 , wherein the processor further executes the shader component to perform anti-aliasing in a single pass operation with the rendering of the one or more edges.

8. A computerized method for generating an object in a mixed reality space, the computerized method comprising: obtaining a two-dimensional (2D) object; determining a thickness and a visibility of one or more edges of the 2D object to be generated to emulate a three-dimensional (3D) thickness; generating a view angle dependent rim drawing of the 2D object having the emulated 3D thickness; rendering the one or more edges with a transparency and color to emulate a lighting condition; and presenting the view angle dependent rim drawing of the 2D object in a mixed reality space.

9. The computerized method of claim 8 , wherein the 2D object comprises a quad user interface (UI) element and further comprising performing an anti-aliasing render of the view angle dependent rim drawing in a same rendering operation as rendering one or more colors for one or more edges of the 2D object defined by the thickness.

10. The computerized method of claim 8 , further comprising separately rendering a horizontal edge color and a vertical edge color of a horizontal edge and a vertical edge of the 2D object, respectively.

11. The computerized method of claim 8 , further comprising transforming a camera world position to a local position of the 2D object in the mixed reality space.

12. The computerized method of claim 11 , further comprising determining the one or more edges to render based at least in part on the transformed position.

13. The computerized method of claim 8 , further comprising using a dot product to calculate a cosine of horizontal and vertical angles between a viewing vector and a normal vector for the 2D object to determine the thickness of the one or more edges.

14. The computerized method of claim 13 , further comprising modifying a result of the dot product based at least in part on a scaling factor such that the thickness of the one or more edges is independent of the scale of the 2D object.

15. One or more computer storage media having computer-executable instructions for generating an object in a mixed reality space that, upon execution by a processor, cause the processor to at least: obtain a two-dimensional (2D) object with four vertices; determine a thickness of one or more edges of the 2D object to be generated, the thickness based at least in part on a viewing vector and a normal vector for the 2D object; generate a rendered 2D object with the determined thickness, including rendering the one or more edges with one or more colors to emulate a lighting condition; and present the rendered 2D object in a mixed reality space.

16. The one or more computer storage media of claim 15 having further computer-executable instructions that, upon execution by a processor, cause the processor to at least render a horizontal edge color and a vertical edge color of a horizontal edge and a vertical edge of the rendered 2D object, respectively.

17. The one or more computer storage media of claim 15 having further computer-executable instructions that, upon execution by a processor, cause the processor to at least transform a camera world position to a local position of the 2D object in the mixed reality space.

18. The one or more computer storage media of claim 17 having further computer-executable instructions that, upon execution by a processor, cause the processor to at least determine the one or more edges to render based at least in part on the transformed position.

19. The one or more computer storage media of claim 15 having further computer-executable instructions that, upon execution by a processor, cause the processor to at least use a dot product to calculate a cosine of horizontal and vertical angles between the viewing vector and the normal vector to determine the thickness of the one or more edges, and modify a result of the dot product based at least in part on a scaling factor such that the thickness of the one or more edges is independent of the scale of the 2D object.
